Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2019-07-
05, which applied to all Airbus SAS Model A318 series airplanes; Model 
A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model 
A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model 
A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 
2019-07-05 required repetitive inspections for cracking of the 10VU 
rack fitting lugs and repair of any cracking. This AD continues to 
require the requirements of AD 2019-07-05, with reduced compliance 
times and removes airplanes having a certain modification from the 
applicability. This AD was prompted by a determination that certain 
repetitive inspection intervals need to be revised. The FAA is issuing 
this AD to address the unsafe condition on these products.

DATES: This AD is effective January 5, 2024.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of January 5, 
2024.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2019-07-05, Amendment 39-19616 (84 FR 
16386, April 19, 2019; corrected May 10, 2019 (84 FR 20542)) (AD 2019-
07-05). AD 2019-07-05 applied to all Airbus SAS Model A318 series 
airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 
airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 
airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and 
-232 airplanes. AD 2019-07-05 required repetitive inspections for 
cracking of the 10VU rack fitting lugs, and repair of any cracking. The 
FAA issued AD 2019-07-05 to address reading difficulties of flight-
critical information displayed to the flightcrew during a critical 
phase of flight, such as an approach or takeoff, which could result in 
loss of airplane control at an altitude insufficient for recovery.
    The NPRM published in the Federal Register on July 13, 2023 (88 FR 
44740). The NPRM was prompted by AD 2022-0266, dated December 22, 2022, 
issued by the European Union Aviation Safety Agency (EASA), which is 
the Technical Agent for the Member States of the European Union (EASA 
AD 2022-0266) (also referred to as the MCAI). The MCAI states that 
during an unscheduled maintenance operation on an A330 airplane, the 
10VU rack was removed for access, and cracks were discovered on 10VU 
rack side fittings on lugs 1, 3, and 4. As a similar design is 
installed on A320 family airplanes, a sampling review was done to 
determine the possible fleet impact. The result showed that several 
airplanes had cracked or broken 10VU rack side fittings. This 
condition, if not detected and corrected, could lead to a high 
vibration level on the primary flight and navigation displays during 
critical flight phases (take-off and landing), possibly creating 
reading difficulties for the crew.
    In the NPRM, the FAA proposed to continue to require repetitive 
inspections for cracking of the 10VU rack fitting lugs, and repair of 
any cracking. In the NPRM, the FAA also proposed to require reduced 
compliance times and to remove airplanes having a certain modification 
from the applicability. The FAA is issuing this AD to address reading 
difficulties of flight-critical information displayed to the flightcrew 
during a critical phase of flight, such as an approach or takeoff, 
which could result in loss of airplane control at an altitude 
insufficient for recovery.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-1409.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from Air Line Pilots Association, 
International (ALPA), who supported the NPRM without change.
    The FAA received additional comments from United Airlines (United). 
The following presents United's comments received on the NPRM and the 
FAA's response to each comment.

[[Page 83814]]

Request To Revise Compliance Time

    United requested revising the proposed AD to add a grace period for 
the reduced compliance times of the repetitive inspections. United 
stated that it accomplished the initial inspections on most of the 
fleet and already scheduled the repetitive inspections within the 
20,000-flight-cycle or 40,000-flight-hour interval specified in AD 
2019-07-05. United pointed out that the repetitive interval is reduced 
to 10,000 flight cycles or 20,000 flight hours in the proposed AD. 
United suggested a grace period of 20,000 flight cycles or 40,000 
flight hours for the first repeat inspection and then 10,000 flight 
cycles or 20,000 flight hours for the following repeat inspections.
    The FAA does not agree with the commenter's request to provide a 
grace period. In developing an appropriate compliance time for this 
action, the FAA considered the recommendations of the manufacturer and 
EASA, the urgency associated with the subject unsafe condition, the 
availability of required parts, and the practical aspect of 
accomplishing the required repair within a period of time that 
corresponds to the normal scheduled maintenance for most affected 
operators. The compliance times are not expected to ground any 
airplanes upon the effective date of this AD. United has not provided 
data for the FAA to consider. However, under the provisions of 
paragraph (l)(1) of this AD, the FAA will consider requests for 
approval of an extension of the compliance time if sufficient data are 
submitted to substantiate that the new compliance time would provide an 
acceptable level of safety. The FAA has not changed this AD in this 
regard.

Request To Allow Flight With Known Cracking

    United requested that the FAA revise the proposed AD to align more 
closely with EASA AD 2022-0266; Airbus Service Bulletin A320-92-1087, 
Revision 04, dated May 16, 2022; and Airbus Service Bulletin A320-92-
1119, Revision 02, dated May 16, 2022. United stated that these 
documents allow further flights up to 5,000 flight cycles, 10,000 
flight hours, or 24 months, whichever occurs first, after any finding 
of cracking on a single 10VU lug. The proposed AD would require repair 
before further flight for any number of lugs found to have cracking.
    The FAA generally does not allow flights with known cracking. 
Therefore, the FAA requires repairing known cracks before further 
flight (although the FAA might make exceptions in certain cases of 
unusual need, as discussed below). This is based on the fact that such 
damaged airplanes do not conform to the FAA-certificated type design 
and, therefore, are not airworthy until a properly approved repair is 
made. While the FAA recognizes that repair deferrals might be necessary 
at times, the FAA intends to minimize adverse human factors relating to 
the lack of reliability of long-term repetitive inspections, which 
might reduce the safety of the type-certificated design if such repair 
deferrals are practiced routinely.
    As noted above, the FAA might allow an exception to these 
requirements in certain cases, if there is an unusual need for a 
temporary deferral and if the temporary fix will maintain an adequate 
level of safety. Unusual needs include such circumstances as legitimate 
difficulty in acquiring parts to accomplish repairs. Under such 
conditions, the FAA might allow a temporary deferral of the repair, 
subject to a stringent inspection program acceptable to the FAA. The 
FAA acknowledges that the manufacturer has specified inspection 
intervals that are intended to allow continued operation with known 
cracks, and to prevent the need for extensive repairs. However, since 
the FAA is not aware of any unusual need for repair deferral in regard 
to this AD, the FAA has not evaluated these inspection intervals.
    The FAA considers the compliance times in this AD to be adequate to 
allow operators to acquire parts to have on hand in the event that a 
crack is detected during inspection. Therefore, the FAA has determined 
that, due to the safety implications and consequences associated with 
such cracking, any 10VU lug that is found to be cracked must be 
repaired or modified before further flight. The FAA has not changed 
this AD in this regard.

Conclusion

    This product has been approved by the aviation authority of another 
country and is approved for operation in the United States. Pursuant to 
the FAA's bilateral agreement with this State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI 
referenced above. The FAA reviewed the relevant data, considered the 
comments received, and determined that air safety requires adopting 
this AD as proposed. Accordingly, the FAA is issuing this AD to address 
the unsafe condition on this product. Except for minor editorial 
changes, this AD is adopted as proposed in the NPRM. None of the 
changes will increase the economic burden on any operator.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Airbus Service Bulletins A320-92-1087, Revision 
04, dated May 16, 2022; and A320-92-1119, Revision 02, dated May 16, 
2022. This service information specifies procedures for repetitive 
inspections for cracking of the 10VU rack fitting lugs, and repair of 
any cracking. These documents are distinct since they apply to 
different airplane configurations. This service information is 
reasonably available because the interested parties have access to it 
through their normal course of business or by the means identified in 
the ADDRESSES section.

Costs of Compliance

    The FAA estimates that this AD affects 461 airplanes of U.S. 
registry.
    The FAA estimates the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.

Inspections (retained actions from AD   2 work-hours x $85 per                $0            $170         $78,370
 2019-07-05).                            hour = $170.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates that it would take about 1 work-hour per product 
to comply with the reporting requirement in this AD. The average labor 
rate is $85 per hour. Based on these figures, the FAA estimates the 
cost of reporting the inspection results on U.S. operators to be $85 
per product.
    The FAA estimates the following costs to do any necessary repairs 
that would be required based on the results of the inspection. The FAA 
has no way of determining the number of aircraft that might need these 
repairs:

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a currently valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to take 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, to: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    The FAA is issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: General requirements. 
Under that section, Congress charges the FAA with promoting safe flight 
of civil aircraft in air commerce by prescribing regulations for 
practices, methods, and procedures the Administrator finds necessary 
for safety in air commerce. This regulation is within the scope of that 
authority because it addresses an unsafe condition that is likely to 
exist or develop on products identified in this rulemaking action.

Regulatory Findings

    The FAA determined that this AD will not have federalism 
implications under Executive Order 13132. This AD will not have a 
substantial direct effect on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
